TUBE AND BAR TROUGH.

Specification of Letters Patent.

Patented Oct. 31, 1911.

To all whom it may concern:

Be it known that we, JOHN S. WORTH and WILLIAM F. HARRISON, citizens of the United States, residing in Coatesville, Pennsylvania, have invented certain Improvements in Tube and Bar Troughs, of which the following is a specification.

The object of our invention is to construct automatic means for discharging tubes, rods, etc., from the troughs or guides which receive the tube or rod from the mill or straightening machine.

A further object of the invention is to so construct the apparatus that the mechanism can be actuated by hand as well as by power means, and a further object of the invention is to so construct the mechanism that a tube of any length can automatically trip the delivery mechanism.

In the accompanying drawings, Figure 1, is a front side view of one end of a tube trough illustrating our invention, Fig. 2, is an end view, Fig. 3, is a rear view; Fig. 4, is a sectional plan view on the line 4-4 Fig. 1, Figs. 5, 6 and 7 are diagram views showing the mechanism in diflerent positions, Figs. 8, 9, 10, 11, 12 and 13 are views illustrating details of the invention, and Fig. 14, is a vertical sectional view on the line l t-14, Fig. 2.

Our invention is particularly adapted for use in tube mills, and the present machine is located directly back of the straightening rolls and receives the tube from the straightening rolls and discharges the tube from one side on to a series of guides which direct the tubes to a test station or storage pile, butit will be understood that the invention can be used in handling rods as well as tubes without departing from the essential features of the invention, and can be located at any point in the mill and at the rear of any of the several machines making up a series in the manufacture of tubes or rods.

A is a trough, V-shaped in cross section and adapted to receive the tube in the present instance from the straightening rolls. In the drawings we have only shown the end of the trough farthest from the rolls, as the invention relates particularly to that portion of the machanism.

B is a shaft mounted in bearings b at one side of the trough A and on this shaft are a series of arms B shaped to conform to the shape of the trough, so that the end arm swings clear of the trough, but the intermediate arms pass through slots a in the trough, as clearly shown inFig. 1. As motion is imparted to the shaft B after the tube is in the trough and the mechanism is shifted to turn the shaft B, then one set of arms B will pick the tube out of the trough and deliver it to skids or guides at one side of the machine.

Our invention rel-ates to certain improvements in automatic mechanism for actuating the shaft B and for bringing the stop mechanism back to its original position. On the 'shaft B is a pinion b which meshes with a gear Wheel 0 on a shaft C mounted in a frame A depending from the trough A. On

the shaft 0, in the present instance, is another wheel 0 which meshes with a rack d on a piston D adapted to the cylinder E having a bracket E secured to the frame A. This is a hydraulic cylinder and the fluid under pressure is admitted through the pipe 6 from the hydraulic valve E which is connected to the source of fluid supply. Carried by the piston D isa cross-head D from which are suspended rods d carrying weights D in the present instance, one on each side of the cylinder E. The weights are sufficient to return the piston to starting point after the pressure has lifted the piston to full upward stroke required.

F is a trip lever which is located at the end of the trough A and in line so as to be struck by the tube as it is fed through the trough. The tube is fed with such force that it will move the arm back to the position shown by dotted lines in Fig. 1, and this movement Will throw in the mechanism for turning the shaft B so that its arms will lift the tube out of the trough. The trip lever F is mounted on a shaft F adapted to a bearing 9 on a bracket G secured to the frame A and on the end of the shaft opposite to the lever F is a gear wheel f which meshes with the gear wheel 6 on a shaft I mounted in bearings g forming part of the bracket G. The other arm f of the lever F is connected by a rod f to the rod h" of the valve H and the piston rod h of the steam cylinder II is connected to the valve stem e of the valve E by links 72, and a lever 72. one arm of this lever being connected to a link h pivoted to the valve casing E. The lever is also provided with a handle by which it can be operated by hand in the event of the hydraulic mechanism being out of order.

lVhile we have described the cylinder H as a steam cylinder, it can be operated by compressed air or gas, and the type of the valve E will depend upon the fluid used in the cylinder E.

Mounted on the shaft I is a lever M hav ing an adjustable weight of on one arm m, the other arm m is forked and spans a shifting rod N secured at its lower end to one of the weights D One portion of the hub of this lever is in the form of a segment, Fig. 9 and the hub of the pinion 2' is also in the form of a segment, Fig. 11, so that when they are set in position there is a. certain amount of lost motion before the two segments contact. Mounted on a stud m on the arm m is a trip pawl 72 having one arm 79 arranged so as to be struck by the projection 41 on the adjustable trip collar n. The trip pawl has a nose p which engages a plate g on the bracket G and holds the lever M until the trip pawl is tripped by the rod N as it is raised on the upward movement of the piston D and the lost motion between the lever M and the gear wheel 2' is sutlicient to allow the gear wheel to move as the lever F is moved outward as it is struck by the tube. By this means the apparatus is made automatic so that after the lever is tripped the weight will carry the lever M down as in Fig. 6, returning the lever F to its normal position and reversing the valve in the valve chest E so as to allow the fluid to escape from the cylinder E, causing the piston D to reverse its movement as well as the rod N. Thus the mechanism is entirely automatic and is under the control of the tube.

In some instances short tubes may be made which would not travel the full length of the trough A. In this event we mount a rod S in roller bearings s at the side of the tube trough and on this rod is an arm S which enters the trough so as to be struck by the tube and on the end of the shaft S is an arm S which is slotted to allow it to pass over the end of the lever F so that any motion imparted to the rod S will actuate the lever F. The arm S is adjustable on the rod S, being fastened to the rod by set screws 8, and has a roller 8 in the present instance, which rests on the inner edge of the trough so as to allow it to travel freely. When long tubes are being made the arm S can be thrown back out of the trough as well as the arm S The operation of the mechanism is as follows: If the tubes are long, then the rod S is shifted so that the tube will strike the lever F and the moment the tube strikes the lever it will force it out, as shown by dotted lines in Fig. 1, and the parts will assume the position as shown in the diagram Fig. 5.

tion to allow the tube to roll to one side the trip collar 11, will trip the pawl 72, releasing it as in Fig. 5, and immediately the lever M will turn to the position shown in Fig. 6, returning the lever F to its normal position, as shown in full lines in Fig. 1. As the lever F returns to its position, the valve H is shifted operating the piston in the cylinder H which in turn shifts the valve in the chest E and the fluid is allowed to escape from the cylinder E. The weights D cause the piston D to move down and the rod N will also move down. The collar n will then strike the arm m of the lever M, as shown in Fig. 7 and will move it, lifting its weight 792 until the trip pawl 29 engages the plate as indicated in Fig. 1, when it will hold the lever M until the trip pawl is again released by the collar a.

We claim 1. The combination of a trough, a rotating shaft having arm for removing a tube or bar from the trough, a trip lever pivoted to a bearing and projecting at the end of the trough so as to be actuated by a tube traveling in the trough, with means for imparting motion to the rotating shaft, and devices between the said means and the trip lever for throwing said means into action, and means for returning the trip lever to its normal po sition after the tube has been removed from the trough.
